Why is a colour made from unequal amounts of red and yellow still considered secondary?

Correct answer: Because both of its components are primary colours

The governing concept is classification by colour components, not by equal quantity or temperature. Red and yellow are both primary pigments, so their mixture remains a secondary colour even when one is used in greater proportion. The unequal ratio may make the result more reddish or yellowish and alter its visual bias, but it does not change the category. Option B is correct; absence of white, an exact orange appearance, or warmth is not the defining rule.
